The latch of the CD V-700 Model 4 is so easily broken that it is almost
useless.

The photo to the right shows what the latch looks like before it gets
broken.

The standard repair (see photos below) involves crimping one end of a
short strip of metal around the metal loop of the latch (attached to the
bottom of the instrument case) and making a "hook" on the free
end. The latter clamps down on the curved plastic fitting for the metal
loop used for attaching the carrying strap.
